The 3PE Coating Equipment Line for Steel Pipe Elbow is an advanced industrial solution designed to apply high-performance three-layer polyethylene (3PE) anti-corrosion coating on bent steel pipes. Engineered for precision and durability, this system ensures consistent coating quality even on complex pipe geometries, making it ideal for pipelines used in oil, gas, water supply, and infrastructure projects.
This specialized 3PE coating line is developed to handle steel pipe bends and elbows, overcoming the challenges of non-linear surfaces. The system integrates surface preparation, epoxy powder spraying, adhesive application, and polyethylene wrapping into a seamless automated process. Equipped with intelligent control systems and precision coating technology, it guarantees uniform thickness, strong adhesion, and long-term corrosion resistance. The equipment is designed to meet international standards, ensuring reliability in harsh environments and extending the service life of pipelines.
Designed specifically for bent and curved steel pipes
Uniform 3-layer coating (FBE + adhesive + PE)
High adhesion strength and impact resistance
Automated control for consistent quality
Energy-efficient and stable operation
